<P>PROBLEM TO BE SOLVED: To provide a photoactive component, especially a solar cell, comprising organic layers and formed by at least one stacked pi, ni, and/or pin diode. <P>SOLUTION: The diodes comprise at least one p-doped or n-doped transport layer having a larger optical band gap than that of a photoactive layer. The individual diodes are characterized by a high internal quantum yield, but can be optically thinned (peak absorption<80%). A high external quantum yield is obtained by either enlarging the optical path of the incident light in the diodes using light traps, or by stacking the diodes into a multilayer (the transition of transition zone between two diodes being facilitated by transition layers for the purposes of improved recombination and generation). Both forms of embodiment have a number of specific advantages using the doped transport layers with a large band gap. <P>COPYRIGHT: (C)2012,JPO&INPIT |
